Hello everyone. I have an iMac G5, which has been running strong until about 3 weeks ago. It started acting weird. Random shutdowns, etc. Then it wouldn't boot. It would just lock up. It would boot into safe boot however. So I researched it. It had a power supply repair extension. So I took it in. Turns out it was the power supply and logic board. I was out of warranty, so they would cover the power supply but not the logic board. Long story short a call to AppleCare and I got them to cover the logic board as well. They fix it. I get it back. I turn it on and the fans are blaring! I mean vacuum style. So I call back the next day and they say, you'll have to bring it in. They said the logic board was causing it and it would need to be replaced. Alright, at this point I am not too happy. A few days later they say the logic boards are out of stock so it could be awhile. They offered to let me take it home, but I declined as I figured it was only a matter of time before the other problems started happening if the logic board was indeed bad. So, I call AppleCare again and explain that the wait is unacceptable. Turns out they did have logic boards. Strange I thought, so the rep gave my local AASP a call told them where to look and gave them another code to say that the repair is covered. That was five days ago. I get a call on the 24th telling me that the logic board is shipping and on the way. Then I get a call today. The service man said that I failed to tell them the computer had been opened and put back together improperly. I know I didn't open the computer. I don't really know much about them, other than specs. So I said, no, I didn't open it. I turned it on, used it for a minute thinking it would be fine, it wasn't so I turned it off. He said he would be calling the AppleCare rep I spoke with and chatting with him about it. Is this something that happens frequently? I know full well I didn't open that machine, so I can't help but feel it is some kind of warranty evasion tactic. That may be extreme, but he is blatantly lying about me having opened it. And I find it suspicious that the problem was diagnosed without having opened it themselves and deciding it was the logic board. At which point could they not have determined than that it had been tampered with? Any suggestions? Thanks, sorry for the long post.
